Auria Link or WIST running two iPad pros together

[AuriaStudios]

Hey forum, my goal is to run two iPads together through one audio interface. This is possible, in theory, from an audio interface called iconnectaudio4+ from iConnectivity.

What I am asking before I purchase the iconnectaudio4+, is will my end game work?. I want Auria Pro on one ipad pro and I want to track Audio from the other ipad pro running Beatmaker 2. I did notice that both apps had WIST capabilities so I can control the midi clock. Would that work? I hate flipping through screens and inter app audio and audiobus. I want a real dual screen IOS experience as I have completely moved to mobile production. I also have dedicated a youtube channel to Ipad Music Production.

Im working on an app and hardware for iPads. I will also be posting this in iConnectivity and Beatmaker 2's forum as well. Thanks a bunch.
